(1) Calculated in accordance with Rule 457(r) under the Securities Act of 1933, as amended (the “Securities Act”). $1,099 of the Registration Fee is being offset in reliance upon Rule 457(p) under the Securities Act against remaining registration fees previously paid in an aggregate amount of $11,022 which were carried forward from Registration Statement No. 333-112604, which was initially filed with the Securities and Exchange Commission by the registrant on February 9, 2004 (“Prior Fee Amount”). The basis for the Prior Fee Amount is set forth in Footnote (3) of the Calculation of Registration Fee table on the cover of Registration Statement No. 333-171596. Taking into account the payment of the current registration fee, in addition to fees paid in connection with prior filings, the registrant will not have any amount remaining available for offset for future registration fees. In accordance with Rule 456(b) and 457(r) under the Securities Act, this “Calculation of Registration Fee” table shall be deemed to update the “Calculation of Registration Fee” table in Registration Statement No. 333-171596.
